I have a 90 civic ex 1.6 and it was mixing water in oil and blowing antifreeze out the exhaust when i got it. pulled head and the gassket was blown. replaced it and the problem remained the same. replaced the head and that fixed the water in the oil but im still blowing antifreeze out the exhaust???? Do i have another bad head or is my block cracked and how do i check it to determine which it is???? [email protected]

If the only symptom is water in the exhaust, maybe try some Bar's Leaks Cylinder Head Gasket Repair. It worked in my 1997 Cadillac Deville Limousine which has a Northstar engine. I had a leaky cylinder after having the system flushed out. Cadillac recommends installing a leak sealant of some sort to help to stop leaks due to inherent imperfections in the head gasket and sealing surfaces.

Be sure to buy the Bar's Leaks Head Gasket Fix for about $30 to try to seal the cylinder head gasket leak. I bought mine from Advance Auto Parts but other auto parts retailers carry it.

It doesn't require draining the system to install it. Just poured it in the radiator and it worked on my Cadillac.
